I-Ethyl Cellulose- EC umthengisi

I-Ethyl cellulose yipolymer engenamanzi ephuma kwi-cellulose, i-biopolymer yendalo efumaneka kwiindonga zeeseli zezityalo. Isetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa amayeza, ukutya, kunye nokunyamekela komntu, ngenxa yeempawu zayo ezizodwa, kubandakanya ukunyibilika, amandla okwenza ifilimu, kunye netyhefu ephantsi. Eli nqaku liza kuxoxa ngeempawu, i-synthesis, kunye nokusetyenziswa kwe-ethyl cellulose.

Iipropathi ze-Ethyl Cellulose I-Ethyl cellulose yimathiriyeli ye-thermoplastic enyibilikayo kwi-solvents ye-organic, njenge-ethanol, kodwa ayinyibiliki emanzini. I-solubility ye-ethyl cellulose inokulungelelaniswa ngokutshintsha iqondo layo lokutshintshwa, elibhekisela kwinani lamaqela e-ethyl ngeyunithi ye-glucose kwi-molecule ye-cellulose. I-Ethyl cellulose eneqondo eliphezulu lokutshintshwa inyibilika ngakumbi kwizinyibilikisi zendalo, ngelixa ezo zineqondo elisezantsi lokufakela endaweni yazo azinyibiliki kangako.

I-Ethyl cellulose iyaziwa ngokuba namandla okwenza ifilimu kwaye ingasetyenziselwa ukwenza ifilimu efanayo kunye nezinzile. Iimpawu zefilimu ze-ethyl cellulose zingaphuculwa ngakumbi ngokufaka iiplastiki, ezifana ne-dibutyl phthalate okanye i-triacetin, eyandisa ukuguquguquka kunye nokuqina kwefilimu. Iifilimu ze-cellulose ze-Ethyl zihlala zisetyenziswa kwishishini lamachiza njengezinto zokugquma iipilisi, iipilisi, kunye neegranules.

I-Synthesis ye-Ethyl Cellulose I-cellulose ye-ethyl yenziwa ngokuphendula i-cellulose kunye ne-ethyl chloride phambi kwesiseko, njenge-sodium hydroxide okanye i-potassium hydroxide. Ukusabela kubandakanya ukutshintshwa kwamaqela e-hydroxyl kwi-molecule ye-cellulose kunye namaqela e-ethyl, okukhokelela ekubunjweni kwe-ethyl cellulose. Iqondo lokuthatha indawo lingalawulwa ngokulungelelanisa iimeko zokusabela, ezifana nokuxinana kwee-reactants kunye nexesha lokuphendula.

Ukusetyenziswa kwe-Ethyl Cellulose Pharmaceuticals: I-cellulose ye-Ethyl isetyenziswa ngokubanzi kwishishini lamachiza ngenxa yobuchule bayo bokwenza ifilimu kunye ne-toxicity ephantsi. Isetyenziswe njengento yokugqoka iipilisi, ii-capsules, kunye ne-granules, eziphucula ukuzinza kwazo kwaye zithintele ukuba zingadibanisi kwi-gastrointestinal tract. Iingubo ze-Ethyl cellulose zingasetyenziselwa ukulawula ukukhutshwa kwamachiza ngokumodareyitha izinga lokuchithwa kwawo.

Ukutya: I-Ethyl cellulose isetyenziswa njengesongezelelo sokutya ukuphucula ukuthungwa kunye nokuzinza kokutya. Idla ngokusetyenziswa njenge-thickener, binder, kunye ne-stabilizer ekutyeni okugayiweyo, okufana neesosi, izinto zokuthambisa, kunye nezinto ezibhakiweyo. I-Ethyl cellulose ingasetyenziselwa ukugquma iziqhamo kunye nemifuno ukwandisa ubomi beshelufu kunye nokuthintela ukubola.

Ukhathalelo Lobuqu: I-Ethyl cellulose isetyenziswa kwiimveliso ezahlukeneyo zokukhathalela umntu, njengezinto zokuthambisa, iishampu, kunye nezinto zokuthambisa, ngenxa yesakhono sayo sokwenza ifilim kunye neempawu zokunganyangeki kwamanzi. Ihlala isetyenziswa njenge-thickener kunye ne-stabilizer kwi-cosmetics kwaye inokusetyenziswa njenge-arhente yokwenza ifilimu kwizitshizi zeenwele kunye neemveliso zesitayile.

Ezinye Izinto Ezisetyenziswayo: I-Ethyl cellulose isetyenziswa kwezinye izinto ezahlukahlukeneyo, njengee-inki, izinto zokwaleka, izinto zokuncamathelisa, neepeyinti. Ihlala isetyenziswa njenge-binder kwii-coatings nanjenge-thickener kwii-inki. I-Ethyl cellulose ingasetyenziselwa ukugquma kwamanzi ephepheni kunye ne-binder ye-ceramics.

Isishwankathelo, i-ethyl cellulose yipolymer engenamanzi ephuma kwi-cellulose esetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa amayeza, ukutya, kunye nokunyamekela komntu. Iyaziwa ngobuchule bayo obugqwesileyo bokwenza ifilimu, ubuthi obuphantsi, kunye neempawu ezinganyangekiyo ngamanzi, nto leyo eyenza ukuba ifaneleke kwizicelo ezahlukeneyo.
